All Yeowww! Catnip toys are completely stuffed with 100% organically grown catnip. No cotton fillers and certainly none of that unfiltered, cheaper 'toy grade' catnip. It's all leaf and flower-top for a more potent, premium blend. Many try to replicate it, but none come close to the quality and originality put into DuckyWorld catnip products. 100% Organic Catnip. No Fillers! No cotton or toy grade Catnip! This is 100% organic catnip leaves only! Made in the USA.
